I'm getting my 1st occurrence of noticeably "out of round" with the cap on Baron pens and I'm asking for any suggestions to try to fix.
I think it may the bushing (or could be the small left spacer after I looked at the photo). I get an ~14 thou concentricity variation on the left side of the cap (you might see the color variation in the photo). I don't have this problem on other pen types using this same mandrel.
Things I've tried already (using the same procedure to tighten the tailstock & mandrel nut where applicable):

Things I've tried already (using the same procedure to tighten the tailstock & mandrel nut where applicable):
- Checked the mandrel -- ~2 thou variance -- think that's ok
- Checked the bushings-only installed on mandrel -- ~3 thou varance
- Checked the bushings and tubes w/o blanks -- ~3-4 thou most places but did vary ~7 thou on the left edge of the cap tube (the problem spot!)
- Remove that small left spacer -- maybe not square on the end and left bushing is twisting a bit when tube-only or tube w/blank installed (more force on outer edge of bushing)? A bit of slop in the bushing might make this worse. Sorry, should have tried this before I posted but didn't think of it until I looked at the photo.
- Buy new bushings.
